Problems solved by technology

[0002] On the assembly line of automobile manufacturing, tire air supply equipment is common and necessary; however, the traditional tire air supply equipment has the following problems: the air path of the air supply machine is long, which leads to the hysteresis of the control, which makes the tire inflation The accuracy is low; the pressure of the tires is difficult to control, which makes the pressure of each tire unbalanced; in addition, the inflation pressure of the tires cannot be observed intuitively, which brings inconvenience to the inflation; Take the value on the pressure gauge to judge the tire inflation situation. This method has a large error and will also reduce the inflation accuracy.

Abstract

The invention relates to a tire supplement-inflating unit, comprising an air source, an air guide pipe and a pressure meter; the center of a dial is vertically fitted with a rotary shaft, and a pointer made of permanent material is fixed on the rotary shaft in a sleeving manner; a piston plate is mounted inside a sealed tube above an air inlet and an outlet nozzle; a pressure spring is connected between the piston plate and the dial; one end of the rotary shaft passes through the dial and abuts to the surface of the piston plate; a regulating power supply is fixed to the lower portion of the pressure meter, and the pressure meter is also fitted with a regulator; a circuit breaker is fitted in the air guide pipe and comprises two opposing heat-expansible plates, and the circuit breaker is serially connected to a circuit of the regulating power supply; the tire supplement-inflating unit enables efficient and accurate inflation, can read pressure value in a tire precisely and can also control air on-off time easily and accurately, thus ensuring inflation precision.

Description

technical field [0001] The invention relates to a vehicle maintenance tool, in particular to an air replenishing machine. Background technique [0002] On the assembly line of automobile manufacturing, tire air supply equipment is common and necessary; however, the traditional tire air supply equipment has the following problems: the air path of the air supply machine is long, which leads to the hysteresis of the control, which makes the tire inflation The accuracy is low; the pressure of the tires is difficult to control, which makes the pressure of each tire unbalanced; in addition, the inflation pressure of the tires cannot be observed intuitively, which brings inconvenience to the inflation; Take the value on the pressure gauge to judge the tire inflation situation. This method has a large error and will reduce the inflation accuracy. Contents of the invention [0003] In view of the above problems, the present invention provides a tire inflator, which can inflate eff...
